I have just used this process to create a statusicon with at red gear, when macro is running.
As the normal icon I used StatusItem.tiff from Iconaholic (the default).
But now this does not show as inverted on a dark menubar.
The red gear shows just as red on the dark menubar and that is okay with me.
Here are the status menuicon: http://cl.ly/152H2d3v3a1r

Is there a way to include inversed version of the icon in the tiff, like with 16x16 and 32x32?
Or how is this accomplished?
